Food Intolerance

The Fitzwilliam FoodTEST – food intolerance test – is a blood test which measures IgG antibody levels associated with specific foods. There is a significant amount of published references indicating an association between elevated levels of these specific IgG antibodies and:

  • Gastro-intestinal issues
  • Irritable Bowel Syndrome (IBS)
  • Migraine / Headaches
  • Obesity
  • Rheumatoid Arthritis
  • Skin Disease
  • Infertility
  • Respiratory symptoms
  • Autism
  • ADHD

Allergy or Intolerance ?

Food ALLERGY describes those cases where the food reaction occurs almost immediately, usually within one hour.. The degree of reaction depends on the degree of sensitivity to the particular food, is obvious and can be violent, even life threatening as with anaphylactic shock..

For example developing a swollen lip or tongue after eating peanuts, or becoming violently sick after eating shellfish – such foods can NOT be eaten again, or the reaction could be far more severe.

True food allergies are quite rare. The affect only a small percentage of the population, and most often develop during childhood.

Food INTOLERANCE affects a great number of people, and can develop at any time of life.. The symptoms of food intolerance rarely occur immediately after the food is eaten – the reaction is usually delayed many hours or even many days. For example, the cheese eaten on Monday could be the cause of Wednesday’s asthma attack Or IBS. It is these delayed reactions which cause which make the detection of the culprit foods a

very difficult task without the help of expert laboratory testing.

What is Food Intolerance

The condition begins when the digestive system is no longer able to process particular foods as they pass down the digestive tract, damaging the

intestinal lining. This contributes / is associated to a condition called ‘Leaky Gut Syndrome’ (LGS) also called ‘increased intestinal permeability’- (not usually recognised by Western Physicians) The end result is a build-up of many toxins – incompletely digested proteins and fats, and waste product. These are absorbed into the bloodstream. This triggers an autoimmune reaction leading to gastro-intestinal problems – bloating, excessive gas & cramps, fatigue, food sensitivity, joint pain, skin rashes, and autoimmunity issues.

Causes are attributed to chronic inflammation, food sensitivity, damage from large amounts of non-steroidal anti-inflammatory drugs (NSAID’s), cytotoxic drugs and radiation, or certain antibiotics, excessive alcohol consumption or compromised immunity.

LGS may trigger / aggravate disorders such as IBS, Crohn’s, Celiac, Arthritis & Asthma, etc.

Laboratory Test

Laboratory Testing is the only reliable / scientific way to test for food intolerance. It only requires a few drops of blood from a pinprick to the finger.

The test grades the degree of intolerance to particular foods. People generally have two or three primary food issues causing many issues along with a small number of secondary foods.

The Irish Times – Arminta Wallace……
“New food intolerance test may mean an end to long lists of forbidden foods and better results.” Note: Eat a broad range of everyday foods BEFORE collecting the blood sample.
